This invention relates to supports for locomotive accessories.

The object of the invention is to provide novel and improved supportsfor power reverse gears, air drums, feed water pumps, air pumps andother locomotive accessories, which supports are characterized bysimplicity, sturdiness and durability and which fur ther reduce boilermaintenance by the elimination of studs or rivets that are now commonlyused in securing the present day form of supports to the boiler.

Referring descriptively to the drawings, the locomotive indicatedgenerally by the designation A comprises an engine bed having side framemembers 1. The side frame members are provided in the usual manner withbrake hanger brackets 2, having bearing lugs 3. In Figs. 2 and 3 thereis illustrated the novel air drum support of the present invention,indicated generally by the designation B. The support comprises a pairof spaced parallel webs 4, having flanges 5 and 6 connecting the websand disposed at right angles toeach other, the flange 5 having holes7'for1ned therein, throughwhich bolts (not shown) are adapted to pass,by means of which the support is secured to the frame 1. The flange 6bears upon and is bolted to the brake hanger bracket receiving supporttherefrom. The webs 4 are connected along their upper edges by a rib 8.Lugs 9 are formed on the upper part of the support extending outwardlyfrom the opposite sides of the webs 4. Holes 10 are provided in the lugs9 and the opposite ends of a U-shaped member 11 are passed through saidholes and secured by nuts 12. A strap 13 of usual construction, forholding an air drum, is provided at its opposite ends with eyes 14 and15. The U- shaped memberll passes through the eye a 14, the opposite endof the strap being disposed between the webs, and a bolt 16 is passedthrough the eye 15, the oppositeends of the bolt passing through holes17 formed in the outer-ends of the webs 4, the opposite ends of thestrap13 being thus secured to the support. The rib 8 is shaped toprovide a substantially horizontal, slightly concave surface 18 and asubstantially vertical, slightly concave surface 19 positioned above thesurface 18, against which surfaces an air drum 37 is adapted to bearwhen held'in position by the strap 13. By drawing up on the nuts 12, thestrap 13 may be tightened around the drum so as to securely hold thedrum in position. As illustrated in Fig. 1, a pair of these supports Bwith straps 13 are employed to support the air drum 37.

Another form of supporting bracket, indicated generally by thedesignation 0, is illustrated. in Figs. '4 and 5. This bracket issuitable for various auxiliaries including air pumps, feed water pumps,power reverse gears, and the like. The support 0 is applied to the frame1 in the same manner as the support B. It comprises a pair of parallelvertical webs 20, joined by a horizontal flange 21 and a vertical flange22 which flanges are at right angles to each other. The flanges 21 and22 are provided with holes 23 and 24, respectively, through which holesbolts (not shown) are adapted to be passed by means of which the supportis secured to the brake hanger bracket 2, and the side frame member 1. Arib 25 connects the upper ends of the webs 20 and a vertical flange 26connects the outer ends of the webs. The flange 26 is provided withbolting seats 27, having holes 28 formed therein for the reception ofbolts by means of which an auxiliary (not shown), of the typehereinbefore mentioned, may be secured to the flange.

In Figs. 6, 7 and 8 there is illustrated the combined valve gear supportand power re verse gear support shown applied to the locomotive A inFig. 1. This support, indicated generally by the designation D,comprises a combined power reverse gear support and valve gear support.The valve gear support is the ordinary style of support for a valve gearof the Walschaert type, and is bolted to the cross-ties 29 of thelocomotive A, in the usual manner, by bolts which pass through holes 30provided in flanges 31 which are formed on the opposite ends of thevalve gear support. The power reverse gear support comprises an invertedU-shaped plate 32 integrally formed on the top of the longitudi nalmember 33 of the valve gear support. Strengthening flanges 34 are formedon the sides of the plate 32.. Bolting seats 35 are provided on one sideof the plate 32 and holes 36 are formed in the seats and are adapted toreceive bolt-s (not shown), by means of which the power reverse gear 38is secured to the support. Suitable lugs 39 are provided in the usualmanner on guides 40, of the power reverse gear, the lugs 39 having holes41 formed therein for the reception of the pow er reverse gear securingbolts. A reverse shaft bearing 42 and bearings 43 for the link trunnionof the valve gear are provided in the usual manner, in the valve gearsupport.

In Figs. 9 and 10 there is illustrated a modified form of the supportD'shown in Figs. 6 to 8. The modified support, indicated generally bythe designation F1, is of the same construction as the support D exceptthat here the inverted U-shaped plate construction of the support D isreplaced by aligned supporting plates or webs 44 which are formed on theupper side of the longitudinal member 33 of the valve gear support. Thewebs 44 are strengthened by flanges 45, and are provided with horizontalbolting flanges 46. Bolting seats 47 are formed on the flanges 46, andare provided with holes 48, for the reception of bolts (not shown) bymeans of which a power reverse gear may be secured to the support E.

Referring to the combined valve gear sup port and power reverse gear.support illus trated in Figs. 11 and 12 and indicated generally by thedesignation F, there is here provided at the right end, a cross-tiemember 49 suitably bolted to the side frame members 50 of a locomotiveand having a supporting flange for a valve gear support and a reverseshaft bearing, of the usual construction formed thereon. At the otherend of the valve gear support the side frame members 50 are connected bya. cross-tie member 51. The cross-tie member 51 is provided withhorizontal flanges 52 at each of its opposite ends by means of which thesame is bolted to the side frame members 50. A longitudinalstrengthening flange 53 is provided on the cross-tie member, andvertical flanges 54 are formed on the outer ends of the cross-tie memberfor securing the valve gear support 55 thereto. The valve gear'support55 and the flanges 54 are provided with aligned holes, for the receptionof bolts (not shown) for securing the support 55 to the flange. Avertical plate or web 56 is extended upward from the flange 53. Thesupporting web 56 is provided with strengthening flanges, 57, around itsedges. Bolting seats 58 are formed on the web 56, and are provided withholes 59, for the reception of bolts (not shown) by means of which apower reverse gear 60 is secured to said support.

Figs. 11 and 12 show the supporting means applied to a locomotive barframe type, but the invention is not intended to be so limited and inplace of such type, any other type of frame may be employed, as forinstance a main bed frame construction and the various parts may beeither separately cast or may be integrally cast with the bed frame orother type. 7

From the foregoing description it will be apparent that by the instantinvention there has been provided a novel and improved supportingmeansfor the various hereinbefore referred to locomotive accessories, whichmeans are characterized by simplicity, sturdiness and durability, whilepresenting in single unitary structuresmeans for accomplishing what washeretofore accomplished by the use of several separate and independentunits. While in the preferred embodiments of the invention the supportswill be formed as integral castings, it will be understood that it iswithin the contemplation of the invention to construct thesame in anysuitable manner. Itis further to be understood that while there has beenhereinbefore described specific embodiments of the instant invention,many and various changes and modifications in form and structure may bemade thereto, without departing from the spirit of the instantinvention, and that all and any such changes and modifications that fallwithin thescope of the appended claims, are contemplated as a part 0 theinstant invention. r
